Hello everyone, in this video, I am going to show you how you can create an account on redhat.com and activate your subscription, that’s free
Going to redhat.com
Click on login and then register now
Select personal as the account type
Write your preferred username
Write your password
Write it again
Here you must write your personal information,
Select your country and give the address,
Click on create my account
If you don’t receive the confirmation email click on resend confirmation email and wait for a second, also check your junk folder
Click on the link in your email
Ok , my email address confirmed
Going to manage account
That is your account summary
Click on the user profile then subscription
You can subscriptions and registered systems here
As you see we don’t have any subscriptions here
Going to developers.redhat.com
Click on login,
After you check the agreements you got free subscriptions
Click on submit
Check the mailbox to activate your subscription
Come back to subscription management and refresh the page
Okay, our free subscription was activated successfully
I will register my RedHat server and assign these subscriptions to that
Again, here is a summary of my subscriptions and registered servers
Connect to the server via putty
Use subscription-manager with the register option
Write the login information
We got the error, I am going to solve this
From the user profile section click on account details
Click on logins and password,
You can see redhat login here,
Again register the server but this time instead of the email I use my RedHat login username
That’s great, server registered
Check what happened in the subscriptions
At the system, we can see one virtual machine, click on view all systems
My server registered and appeared here , click on the hostname of the server
The server is registered but it does not have any subscription
Click on subscriptions
Use run auto-attach to automatically assign subscriptions to this registered server
Also, you can see the status that shows us properly subscribed
I am trying to check the subscription status from the server with subscription-manager with the list option
Try to install some package
We got the error because our repositories are not activated, to refresh repositories and list them use subscription-manager with repos option
Try to install the package again
That is installed

Hello everyone today I am going to install oracle 19c on Linux RedHat 8.6. also in this video, I will talk about x11 forwarding and its problem, and install oracle 19c on the new version of RedHat
This is my RedHat server, I am going to check the subscription status of this server with subscription-manager with list option. In my channel, you can find another video related to subscription-manager
Check Linux updates with the yum update command
I always use nano as a text editor, so trying to install it
Yes
Check the IP address of this server
We have to config hostname of this server to install oracle
Open the hosts file and edit IP and hostnames for this host,
Pres control x and then yes to save these changes
Going to the temp directory
We can prepare oracle prerequisites manually or by downloading one package and installing it everything will be prepared automatically to do this just paste this command to download the installer package and with yum you can install it, below you can find all commands that require during the installation
In the prerequisites we have just set the password of the oracle user, as you know we can not install oracle DB as a root, all groups are created automatically with the previous script,
Now that is time to disable SELinux , to do that open config file
Change enforcing to disabled
Control x and y to save
Stop the firewall service and disable it
We install all the xterm and xorg packages to enable x11 forwarding and get the graphical interface throw ssh
Create DB home directory, as I told you can find upper commands
Create ora data directory
set oracle user and oinstall group owner to u01 and u02 directory
set oracle user and oinstall group permission to u01 and u02 directory
reboot server
as you can see after xterm and xorg packages installed , x11 forwarding enabled here
with xhost + you can connect to GUI throw the ssh from any host
create a script directory in the oracle user home directory
create a script and name it setenv.sh to import oracle required variables
paste these lines in it and save
whit this command make this script as user startup script, that means every time oracle user logging into the system this script automatically will be execute
also, give the permission to oracle user to run this script with these commands
now I am going to download oracle database installer file
this is the oracle database installer for the Linux , you can download it from here
click on download linux x64……
after you give the username and password, download will start, Creating an account on oracle website is free and its very easy
ok , oracle installer file downloaded, now login in as oracle user
when you are using x11 forwarding , if your client and server are on the same subnet do not require open any port in the firewall but when you are on a different subnet you have to open port 6000 in the firewall , you can see the direction of that port and ssh direction. that’s very important because if your port is not open you got an error during oracle installer
set the display variable with this command, 10.10.10.38 is my client ip address ,
check the oracle home variable
going to oracle home directory
upload downloaded file to this directory
unzip this file with o and q parameters
because I am trying to install oracle 19c on RedHat 8.6 I have to change cv_assume_disting to the latest supported version in the config file ,
to do this uncomment this line and instead of oel5 write rhel7.9 and save it, if you don’t do that you got an error during installation
Now we can run the installer
Come back to oracle home directory
Execute runinstaller
ok , you can continue this wizard based on your requirements
you can also follow my steps to install oracle database
you can ignore this warning,
this is a summary of the installation, after clicking on install, oracle database will be installed
ok , oracle database installed , if you run netstat you can see port 1521 , is oracle default port is on listening status and everything works fine,
